a lication filed February at, lair. Serial in. 150,666.

To all whom it may concern:

Be it known that l, JACOB Fnnenn, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Typeriting Machines, of which the following is a specification.

My invention relates to typewritin'g machines, and more particularlylto dust guards for protecting the pivotal hearings of the type hars.

As is well understood ruhhings, comprismg particles of sand, ruhher and paper, fall from the front face of the platen in a front strike typewriting machine and find their way into the type-bar hearings and clog the operation of the type actions, unless efiicient means are provided to prevent this. It has been" found in practice that such ruhbings will also find their way into the hearings from the rear of the type 'har segment, as well as from the front thereof, especially when the universal. her is of such a charactor that it extends beyond the rear face of the scent.

The main ohject of my invention, generally stated, is to provide simple and eiilfor preventing such ruhhings from entering the type-liar hearings from the rear of the type-bar segment.

To the above and otherends which will hereinafter appear my invention consists in the features of construction, arrangements of parts, and comhinations of devices, set forth. in the following description and partiedlarly pointed out in the appended claims.

in the accompanying drawings, wherein. like reference characters designate corre sponding parts in the various views,

Figure 1 is a detail fore and sectional. view, showing a number of parts of a fronttrike typewriting machine, my invention embodied therein.

Fig. is a detail rear view of the same.

Fig, 3 is a detail fragmentary perspective view of the some, sho i g in addi ion t e aft vertical connections from the universal bar to the escapement.

Fig. 4 is a detail fragmentary fore and aft vertical sectional view of a modified form of the construction.

Figs. 5 and 6 show in vertical section and rear elevation respectively a further modified form of construction.

F i 7 and 8 are corresponding views of a sti 1 further modification.

Figs. 9 and 10 are corresponding views of another form of construction embodying my invention.

Figs. 11 and 12 are corresponding views illustrating the 6th form of construction embodying my invention.

Fig. 13 is a detail fragmentary top plan view of the parts represented in Fig. 12.

Fig. it is a detail face view of the hlanlr from which the universal bar and supporting member shown in Figs. 11 to 13, inelusive, are formed.

Referring first to F igs, l, 2 and 3 it will he understood that a substantially vertically disposed type-bar segment, designated as a whole by the reference numeral 1, is mounted in the usual or any suitable manner below the platen 2. in the present instance the segment is a solid or closed segment with the rear face 8 thereof in a plane which is forward of the front face of the platen. The lower edge of the segment is slotted through from front to rear, the heel 4c of a type har 5 working in each radial slot 6, so that each type bar is guided in its movement by the side walls of the slot in which it works. The type hars are mounted on a pivot wire Z, TGC'BlVGtl in a groove 8 in the rear face of the segment at the slotted portions thereof. The slots '8 are closed on their upper sides by a continuous segmental flange or rih d, which as heretofore overlies the heels of the type here which work in the slots. Each type har has a. recess a to enable it to clear the part 9 in the movement of the typehar to printing position. The said flange or rih 9 constitutes a forwardly er tending dust guard which tends to prevent till Ill

lit;

the admission of falling particles of dust or grit from entering the bearings of the type-bars from the front of the segment. The type-bars may be actuated by the usual or any suitable means and each bar is provided at its heel with a shoulder or cam 10 which, as the type approaches the printing position, strikes or co-acts with the, forward edge of a segmental universal bar 11. It will be observed that the universal bar works in a segmental groove or recess in the rear face of the segment and extends beyond the such rear face to a position where, unprotected, it would catch rubbings which drop from the front face of the platen to the rear of the segment; and such rubbings eventually would be apt to work their way into the type-bar bearings, injuriously affecting them and also interfering with the free and true operations of the type-bars. By my invention this is all prevented.

In each of the constructions shown I have provided a dust guard or shield which overlies the universal bar in rear of the typebar segment and which preferably is of such curvature and length as to cover or protect all of the slots at the rear side of the segment and prevent particles of grit falling from the platen to the rear of the segment from lodging on the universal bar and entering the slots. This dust guard or shield is either fixed to, carried by, or formed integral with the universal bar, and hence moves, therewith in the movements" of'the latter caused by the striking of the typebars.

In the construction shown in Figs. 1, 2 and 3 the curved dust shield is shown formed integral with the universal bar 11, and comprises a vertically disposed wall'12 connected with a downwardly and rearwardly inclined roof or cover 13, which may be designated as the dust guard'proper. The forward upper edge of the roof normally bears against the rear face 3 of the segment above the rear ends of the slots 6. The roof 13 at each end may be formed with an extension 14 which closes the space between the roof and universal bar at the ends thereof, as best shown in Fig. 3. It will be understood from an inspection of Fig. 2 that the dust guard is segmental, conforming in general contour to the universal bar. The combined universal bar and dust guard thus formed is supported and guided in its movements by any suitable means such as by guide pins 15, each riveted at one end to the dust shield and working loosely at its other end in a guide opening in the segment.

It will be understood that in this form of construction the inclination of the roof 13 of the dust guard tends to shed the falling particles. It will also be understood that even though the dust shield be moved out of contact with the rear face of the segment,

from the full line to the dotted line position in Fig. 1, during the printing movement of the type bar, this does not affect the usefulness of the dust guard since it is only when the dust guard is in its normal rest position that erasures are made on the paper in the machine and at that time the universal bar and the type-bar slots are fully covered and protected by the dust guard.

The universal bar may be operatively connected to the escapement by any suitable means. In the present instance I have shown a link 16 pivoted at one end, at 17, to a dog rocker 18. The opposite end of the link is bifurcated and connected by the forward arms thereof, as at 19, to the dust shield. The dog rocker is thus under control of the universal bar to control the escapement wheel 20, and paper carriage, not shown.

In the construction shown in Fig. 4 the segment 1 is made thicker or heavier adjacent to the top walls 9 of the slots and is provided with a segmental recess 21 in the rear face thereof, said recess being concentric with the recess in which the universal bar works. The dust guard is shown made integral with the universal bar 11 and is formed with an inclined roof 13 from which projects forwardly a segmental flange 22. This flange is received in the segmental groove or recess 21 in the rear face of the segment and remains therein at all times. In other words, the length of the flange 22, fore and aft of the machine, is such that it cannot be wholly withdrawn from the groove 21 in the rearward movement .of the dust guard with the universal bar. By reason of this fact the universal bar and rear ends of the slots are protected at all times, irrespective of whether the machine is in operation or at rest. The combined universal bar anddust guard shown in this figure may be supported on the segment by guide pins 15 riveted to a suitable sheet metal arm or upright 23 which in turn may be riveted as at 24 to the universal bar.

The construction shown in Figs. 5 and 6 is similar to that last described except that the flange 22 is omitted, the upper edge of the roof l3 bearing against the rear face 3 of the segment when the shield is in normal position. The other parts of these figureswhich correspond to those previously described are designated by corresponding reference characters, 15 designating the supporting pins.

In the construction shown in Figs. 7 and 8 the universal bar 11 and dust shield are integral, the parts forming a single member which is substantially U-shaped in crosssection. The forward edge portion of the segmental roof 13 of the dust shield e xtends into a recess, or segmental groove 25 in the rear face of the scent, as in the construction disclosed in Fig. i, and with like effect. Supporting and guiding pins 15 are riveted directly to the dust guard and work in guide openings in the scent.

In the construction shown in Figs. 9 and 10 the dust guard and universal bar are made of separate parts but are fixedly connected together, This enables the dust guard to be made fromthinner and lighter stock than that from which the universal bar is formed. In this construction the dust guard has an inclined roof 13 which bears at its forward edge against the rear face of the segment. The dust guard is formed with perforated ears 26 secured by means of bolts and nuts, 27 and 28, respectively, to perforated ears 29 formed on an upstanding flange 30 on the universal bar 11. This flange carries guide pins l5 by which the universal bar and dust guard. are inovably supported on the segment. a

The construction disclosed in Figs. 11 to 14, inclusive, is similar to that shown in Figs. 5 and 6, except that in the former the universal bar and dust guard are made as separate parts. Thus, in Figs. 11 to 14:, the universal bar 11 is recessed at its rear edge, as as 31, for the reception of lugs 32 formed on the lower edge of an inclined roof 13 of the dust guard. At the points where the lugs 32 are received in the recesses 31 the universal bar and dust guard may be connected by riveting, spot-welding or brazing the members together. A suitable upwardly projecting sup orting arm or plate 33 may be formed on t e universal bar for supporting the guide pins 15.

In each of the modified forms of construction shown extensions corresponding to the extensions 14: in Figs. 1, 2 and 3 may be provided, either on the universal bar or dust guard, to span the end openings between them. These extensions are designated in Figs. 4, 6, 8 and 10 by the reference characters 148, 14:, 14 and 149, respectively.

It will be observed, moreover, that in each of the constructions disclosed the member comprising the universal bar and dust guard is trough-shaped in cross-section, one side or portion thereof constituting a universal bar and the other side or portion constituting the overlying dust guard which protects the universal bar and the slots at the rear of the segment.

In all instances but one the dust guard is formed or provided with a downwardly sloping or inclined roof or portion, whereby the descending rubbings or particles tend to fall away and behind upon striking the roof. Any particles that may remain on the roof are, however, shaken 0d" and fall to the bot tom of the machine or upon the table during the vibration of the dust guard with the universal bar under the printing action of the typebars.

arious changes may be made without departing from my invention.
